Geraniol,a volatile organic compound,is a component of rose oil. The density of the vapour is $0.46 \, g \, L^{-1}$ at $257^{\circ} C$ and $100 \, mm \, Hg$. The molar mass of geraniol is $....$ (Nearest Integer) [Given $R = 0.082 \, L \, atm \, K^{-1} \, mol^{-1}$]

At what temperature in $^\circ C$ will the volume of a gas become double its volume at $0\,^\circ C$?

$A$ $100 \ L$ cylinder containing $H_2$ exerted a pressure of $4 \ atm$ at $300 \ K$. It was accidentally opened and some $H_2$ escaped. When it was closed,it exerted a pressure of $3 \ atm$ at $300 \ K$. The number of moles of $H_2$ remaining in the cylinder is equal to (Assume $H_2$ as an ideal gas; $R=$ gas constant)

At constant temperature and pressure,what is the volume of $n$ moles of different gases?

Pressure of a mixture of $4 \ g$ of $O_2$ and $2 \ g$ of $H_2$ confined in a bulb of $1 \ L$ at $0^{\circ}C$ is $..... \ atm$

An open vessel at $300 \ K$ is heated until $2/5$ of the air in it is expelled. Assuming that the volume of the vessel remains constant,the temperature to which the vessel is heated is $..... \ K$.
